2.3.3. USB Connector – USB Type-C
The Serial connector supports USB-C 2.0 cables without the SuperSpeed pairs. Therefore connecting a fully
featured USB-C 3.1 cable will not provide SuperSpeed functionality, although the cable will still work as per
the USB 2.0 specification. When connected via the USB port, the THCD-101 will emulate a standard serial port.
The fixed baud rate is 57600 with other settings as follows: 8 data bits, 1 stop bit, No parity, No handshaking.
2.3.4. Power Input Jack
The panel meter display requires a 24Vdc ± 5%, 600mA supply to operate. This must be a rectified and
regulated direct current supply capable of supplying at least 1.1 Amp during the turn on surge. Although the
THCD-101 has an internal fuse and power supply overload shutdown protection, the supply to the THCD-101
should be protected by fuse or other suitable electronic method.
For convenience, Hastings offers a compatible supply (12-01-169) that, when matched with the US (12-01-160),
Euro (12-01-164) or the UK (12-01-165) plug adapters, converts wall power to specified levels
A standard 5mm diameter ‘dc power jack’ is required to connect to the THCD-101.
Connect the positive conductor to the center pin. Connect the negative (0V) conductor to the outer of the
jack.
WARNING: Ensure correct power supply rating and polarity. Do not use a partially assembled
or faulty unit. Incorrect use of this equipment, or use in a manner not specified may impair
the user’s protection.
